The relevant sentence from the link: I would very much like to reach the point where we are able to provide access to some digital surrogate of the game while keeping the original disc in storage in the same way that we provide access to digital surrogates of our film and video collection fiberoptically to terminals in the Moving Image reading room.
Even if they can't figure out a way to do that, the material should become freely available after copyright expires. It might take 120 years for that to happen, but better late than never.
I've never done it, but I believe the answer is "yes". I believe you can go to the physical library of congress and view their archived media. I don't believe you can check it out or distribute it without the copyright holders permission, but I think you can view it while you're there.
Again, never done it, only seen stuff in YouTube videos, and not even recently.
